I'm also seeing this warning, or something very much like it, as below:

[    7.382345] ------------[ cut here ]------------

This happens repeatedly every couple of minutes after my computer has
booted. It looks like this is pretty recent; I don't recall seeing it on
2.6.36-rc4-00076-g9c03f16. If nobody has any ideas regarding the cause,
I can try bisecting it to narrow it down; let me know!
